Comparison of De-Epithelialized Gingival Graft With or Without Platelet Rich Fibrin in Multiple Gingival Recessions

The aim of this study is to compare the clinical efficacy and patient reported outcome measures of de-epithelialized gingival graft (DGG) with or without platelet rich fibrin on treatment of multiple adjacent gingival recessions with coronally advanced flap (CAF) technique.

Fifteen patients with split-mouth multiple gingival recessions affecting at least 3 adjacent teeth will be treated with either DGG or DGG+PRF. Recession depth(RD) and width(RW), probing depth(PD), clinical attachment level(CAL), keratinized tissue width (KTW), gingival thickness(GT), and percentage of root coverage (RC%) will be evaluated at 1, 3 and 6 months postoperatively. For patient reported outcome measurements, oral health impact factor-14 (OHIP-14) scores, postoperative pain, bleeding, discomfort and painkiller consumption will be recorded. A total of 15 patients will surgically treated with coronally advanced flap (CAF) associated with de-epithelialized gingival graft. Groups were defined as DGG and DGG+PRF: DGG Group (n=15): de-epithelialized subepithelial connective tissue grafts + coronally advanced flap DGG+PRF Group (n=15): de-epithelialized subepithelial connective tissue grafts+ L-Platelet Rich Fibrin + Coronally advanced flap
